WASHINGTON — Scores of Wall Street financiers will get a chance to bend President Obama’s ear when he heads to the aptly-chosen Purchase, N.Y. for a major fundraiser with one of his top bundlers Friday.

The event is being held at the home of Robert Wolf, former CEO of UBS Americas, who now heads 32 Advisors, Democratic sources told The Post.

The event is being billed a “Labor Day barbecue” for 250 high-rollers kicking in up to $32,000 each, which sets up the Westchester event to be a huge cash haul for the Democratic National Committee at a time when the party is fighting headwinds in the off-year elections.

Wolf golfed with Obama on the president’s vacation on Martha’s Vineyard earlier this month, joining a foursome that included private equity investor Glenn Hutchins.

Wolf, a close Obama pal, bundled more than $1.3 million for the president and Democrats during Obama’s reelection — placing him in an elite group who raised more than $1 million, according to a 2012 New York Times report.

It’s the latest in a string of trips Obama has made to the New York cash machine, with the mid-term elections just 10 weeks away. Obama visited New York six times in the last three months.

Not every guest will be a hedge funder. The winner of a small donor contest to “barbecue with Barack” also gets to attend along with a guest.

As a key Wall Street emissary to Obama, Wolf has sometimes taken the sting out of Obama’s more biting criticisms of Wall Street, an industry he’s both courted and criticized, like when he lambasted “fat cats” in 2009.

“I said ‘Mr. President, I know you think I’m overweight, but I can think of better names to call me,'” Wolf told the Wall Street Journal. “He laughed.”

After Friday’s event, Obama flies to well-heeled Newport, R.,I. for an event to benefit House Democrats. Tickets will go for $10,000 to $32,000, a Newport NBC affiliate reported
